    • Transfer Learning for Illustration Classification 

      Lagunas, Manuel; Garces, Elena (The Eurographics Association, 2017)
      The field of image classification has shown an outstanding success thanks to the development of deep learning techniques. Despite the great performance obtained, most of the work has focused on natural images ignoring other ...
    • Transferring Facial Expressions to Different Face Models 

      Orvalho, V. Costa Teixeira; Zacur, Ernesto; Susín, Antonio (The Eurographics Association, 2006)
      We introduce a facial deformation system that helps the character setup process and gives artists the possibility to manipulate models as if they were using a puppet. The method uses a set of labels that define specific ...
    • Transient Photon Beams 

      Marco, Julio; Jarosz, Wojciech; Gutierrez, Diego; Jarabo, Adrian (The Eurographics Association, 2017)
      Recent advances on transient imaging and their applications have opened the necessity of forward models that allow precise generation and analysis of time-resolved light transport data. However, traditional steady-state ...
    • Tree Variations 

      Argudo, Oscar; Andújar, Carlos; Chica, Antoni (The Eurographics Association, 2017)
      The cost-effective generation of realistic vegetation is still a challenging topic in computer graphics. The simplest representation of a tree consists of a single texture-mapped billboard. Although a tree billboard does ...
